BEAM-ER.

Specification of Letters Patent.

Patented May 28, 1918.

Application filed May 24, 1917. Serial No. 170,744.,

To all whom it may concern:

Be it known that I, FANNIE LELA LEE, a citizen of the United States, residing at, laducah, in the county of McCracken and State of Kentucky, have invented a new and useful Reamer, of which the following is a specification.

The present invention appertains to ream ers, and aims-to provide a novel and improved device for reaming'out or'truing bearings, journal boxes, and the like.

The invention has for, its object the provision of a reaming device, which although comparatively simple and inexpensive in construction, is thoroughly eihcient and practical for reaming out or truing bearings and journal boxes of various types and for various uses, the parts being adjustable and interchangeable in order that bearings of various sizes and internal diameters may be operated on.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein igure 1 is a plan view of the improved device.

Figs. 2, 3, and 4 are cross sections on the respective lines 2-42, 3-3, and 44 of Fig. 1.

Fig. 5 is av fragmental plan view of one of the bearing-supporting bars, illustrating a modification.

In carrying out the invention, there is provided the bed or base plate 1, preferably of elongated or rectangular form, which has threadedly or otherwise attached thereto, near its ends, the pairs of laterally spaced upstanding posts 2. Reamer bearings or seats 3 have their ends slidable vertically upon the posts 2, said bearings being disposed between the posts ofthe two pairs, and being guided for vertical movement. The bearings 3 are supported on set screws 4 threaded upwardly through the base plate between the posts,- wh eby the bearings '3 can be adjusted vertically accurately by rotating said screws. Caps 5 for the bearings 3 have their terminals slidably engaging the posts above the bearings 3, and said caps are yieldably depressed by means of coiled wire expansion springs 6 surrounding the posts and confined between the caps 5 and nuts 7 threaded on the upper terminals of said posts.

The reamer propergdesignated 8, is of elongated cylindrical form, being provided with flutes in its periphery providing cutting edges. This reamer is carried by a shaft 9, or terminal trunnions, supported by and journaled in the bearings 3 and held thereon by the caps 5, which are pressed downwardly by the springs 6 to seat the shaft 9 in the bearings 3, and seat said bearings on the set screws 4. The shaft 9 is provided at one end with a crank handle 10 for manually rotating the reamer, although said reamer can be rotated by any suitable means whatever. The bearings 3 adjustably support the reamer, since the set screws 4c in being rotated will raise or lower the bearings 3 with which the reamer is shiftable vertically. The reamer 8 is disposed longitudinally above the base.

The bearing sections are supported astride the reamer by a pair of parallel longitudinal bars or supporting rails 11 seated on the said plate adjacent to the side edges thereof. Screws 12 are threaded upwardly into the bars 11 near the ends thereof, and extend through transverse slots 13 in the said plate 1, whereby when the screws are loosened, the bars 11 can be adjusted transversely, whereby they can be spaced apart different distances at the opposite sides of the reamer. The reamer extends longitudinally between the bars 11, and in order to clamp a bearing section 18 on the bars 11, they are provided with upper T-shaped grooves 16 extending from end to end and receiving the heads of upstanding bolts 17 slidable along the bars 11, and adapted to project upwardly through the apertures of the bearing section 18 which has its terminals seated on the bars 11, so that said bearing section or member is astride the reamer,

as seen in Fig. 4:. Nuts 19 are threaded on the bolts 17 to clamp the bearing member 18 upon the bars 11. A plurality of pairs of bolts 17 can be used for holding a corresponding number of bearings, when desired,

and plungers 25 are slidable through the arches to rest upon the shaft 9, the upper ends of the plungers 25 acting as pointers, to indicate upon the graduations of the standards r24e, the position ot thereamer shaft.

The bed plate lis provided with openings 26 between the bars 11 through which the metal shavings can drop, and the bed plate is further provided at its central portion ith a depending lug 27 adapted to be held in a vise orother support, for supporting the device.

The reamer 8 can be used interchangeably with other reamers of different diameters, whereby bearings of various internal diameters can be reamed out or trued, by interchanging the reamer, this being readily, done by removing thenuts 7, springs 6 and caps 5. lnreaming out or truing a bearing, a reamer 8 of proper diameter inserted, and the bars 11 are then adjusted to accommodate the particular hearing or journal box, which is clamped on said bars astride the reamer. T he reamer then adjusted verti cally so as to be concentric with the bearing, this being done by adjusting the set screws it, while the plungers 25 will indicate the position of the reamer, in order to bring its axis into proper line. As the reaming action is started, the nuts 19 can be loosened, and then as the bearing is reamed out, the nuts 19 can be tightened, until the bearing 18 is clamped on the bars 11, which will complete the operation. Or, instead of pressing the bearing downwardly to ream it out, the reamer can be raised from below during the rotation thereof, until concentric with the bearing, to completely ream out the bearing and true it.

' Instead of providing each bar 11 with the groove 16, the same can be provided with a longitudinal series of threaded apertures 16 for receiving bolts for clamping the bearing members on said bar, such modification be ing shown in'rig; 5.

Having thus described the invention, What is claimed as new is 1. A reaming device embodying bars disposed side by side, a reamer mounted for rotation between said bars longitudinally when M v eane /e thereof, and means for securing hearings on said bars astride the reamer, the reamer proecting partially from between the bars to engage a bearing disposed astride thereof.

2. A reaming device embodyinga pair of bars, means for mounting said bars for adjustment toward and away from one another, a reamer mounted for rotation between saidbars and for adjustment to project more or less from between said bars, and means for securing bearings on saidbars astride the reamer.

3. A reaming device embodying a bed plate, bars mounted,adjustably thereon for movement toward and away from endanother, a reamer disposed longitudinally between said ba-rs, means carried by the bed plate for adjustably supporting said reamer to project more or lessfrom, between said bars, and means for clamping hearings on said bars astride the reamer.

4:. A reaming device embodying a bed plate, posts carried thereby, supporting bars mounted on the bed plate for adjustment toward and away from one another, bearings; slidable on theposts, means Y for adjusting ,said bearings, a shaft seatedin said bearings and having a .reamer between said bars, means for securing bearing members on saidbars astride thereamer, caps for said bearings slidable upon the posts, and spring means upon the poststor pressing the caps toward the bearings.

A reaming device embodying a. bed plate, pairs of posts carried by the bed plate near its ends, parallel bars disposed longitudinally upon the bed plate, means attaching the bars to the-bed plate for transverse adjustment, bearings slidable upon said posts, a shaft seatedin said-bearings and having a reamer between said bars, set screws threaded through the bed plate and supporting said bearings for adjustment, means for securing hearings on saidbars astrideithe reamer, caps slidable upon the posts to hold the shaft seated in the first mentioned bearings, and springs upon the posts pressing the caps toward the bed plates. 7
